EDWARD M. ORANDAL, OF MARSHALLTOWN', IOWA.

Letters Patent No. 108,006, dated October 4, 1870 antedated September26, 1870.

To all whom -i t may concern Be it known that I, Enwium M. CRAXDAL, oflilarshalltown, in the county of Marshall and State of Iowa, haveinvented certain new and useful Improvements in Lit'e-Preservers; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, reference being bad to the accompanying drawingsand to the letters of reference marked thereon, which form a part ofthis specification.

My invention consists in the combination and arrangement of the partshereinafter set forth.

in order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, rcibrriug t0 the annexed drawings, whichrepresent a perspective viewot' my lite-preserver.

A represents a sack, made of very thin vulcanized rubber, covered with asuitable silk covering, and rendered air-tight. This sack is placedaround the body,

inunediately under the arms, and under the shirt. It

is prevented from sliding down by means of the straps B B, which passover the shoulders, and itcan be inflated with air at any moment bymeans of the tube v. G, which leads into the sack, and is provided withasuitable valve for retaining the air.

When an emergency arises the person wearing the lii'e-preserver canreadily unbutton the shirt, and place the tube to the mouth to inflatethe sack, making it. impossible for the person to get his or her headunder water.

By being able to wear this when on the water, and knowing it can beinflated in a moment insures coniidence, and thereby prevents theahscnt-mindedness which is caused by sudden fear.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letter Patent, is-

The combination of a flexible band, A, tube (1', and straps B B, allarranged to operate substantially as and for the purpose described.

In testimony that I claim the foregoing as my own, I aflix my signaturein presence of two witnesses.

. EDWARD M. CRANDAL.
